SummaInstall

Overview

This node, named "Summa," is designed to interact with the Summa API (version indicated dynamically). It supports multiple resources and operations related to telecommunications subscriptions and services. Specifically, for the IMS Subscription resource and the Remove Public User Identity operation, the node facilitates removing a specified public user identity from an IMS subscription.

Common scenarios where this node is beneficial include managing IMS subscription data in telecom environments, automating subscriber profile updates, or cleaning up obsolete public identities associated with IMS subscriptions.

For example, a telecom operator could use this node within an automation workflow to remove a public user identity when a subscriber changes their service plan or terminates a contract.

Properties

Output

The node outputs JSON data representing the result of the Remove Public User Identity operation. This typically includes confirmation of the removal action, status codes, or any relevant response data returned by the Summa API.

If the operation involves binary data (not indicated here), it would represent files or attachments related to the IMS subscription update, but no such binary output is evident from the provided code.

Dependencies

• Requires an active connection to the Summa API via an API key credential configured in n8n.
• Uses internal helper classes for HTTP requests, state management, and operation resolution/execution.
• The node depends on the summaApi credential for authentication.
• No additional external services beyond the Summa API are indicated.

Troubleshooting

• Authentication errors: Ensure the API key credential for the Summa API is correctly configured and valid.
• Invalid Public Identity: If the provided public identity does not exist or is malformed, the API may return an error. Verify the identity format before execution.
• Network issues: Connectivity problems with the Summa API endpoint can cause request failures.
• Operation not supported: If the resource-operation combination is incorrect or unsupported, the node may fail to resolve the operation method.

To resolve these:

• Double-check credentials and permissions.
• Validate input parameters carefully.
• Confirm network connectivity and API endpoint availability.
• Review API documentation for correct usage of the Remove Public User Identity operation.
